1.对图中每一个点,都用nearest neighbour algorithm找到一条走过每个点的路径。 2.在1中找到的所有路径中,取最短的一条。(实际考试中往往只要求对少部分点使用这种方法) 如果题目要求这两种方法都用,那么取两者结果中较短的作为upper bound。 找lower bound有一种方法。 1.去掉图中的某个点及与其连接的边。
然后走完这两行。接着按LLLLDRRRR这种路径往下走。 通过YY可知绕的时候事实上就两种情况,于是就能够写了…… #include #include<string> #include<cstring> #include<cstdio> #include<cstdlib> #include<cmath> #include<queue> #include<vector> #include<iostream> #include<algorithm> #include<bitset> #inc...

简单来说,Travelling Salesman Problem (TSP) 是最基本的路线问题。它寻求的是旅行者由起点出发,通过所有给定的需求点后,再次返回起点所花费的最小路径成本,也叫旅行商问题、旅行推销员问题、货郎担问题…… 当然,如果你非要把TSP理解成“内容服务提供者”(Telematics Service Provider)小编也不会打你……计算机网络...

Solving NP hard problem like Travelling Salesman Problem (TSP) is a major challenge faced by analysts even though many techniques are available. Many versions of Genetic Algorithms are introduced by researchers to improve its performance in solving TSP. Clustering Genetic Algorithm (CGA) was recently...
This article presents the Ant Colony Optimization algorithm to solve the Travelling Salesman Problem. The proposed algorithm implements three novel techniques to enhance the overall performance, lower the execution time and reduce the negative effects particularly connected with ACO-based methods such as ...
利用动态规划求解旅行商问题(Travelling Salesman Problem,简称TSP)在之前的推文中已经有了详细的介绍,今天我们要对这个问题进行更深一步的探索,即随着问题规模的变化,使用动态规划算法求解TSP耗费的时间是多少?耗费的计算机内存又是多少?这都值得我们进一步去探索,为此,我们特地做了一组实验来探索上面的问题。我们实验中...
